Part Design Guidelines for the Plastic Injection Molding Process

Injection Molding Design GuidelinesFor design engineers who are new to designing for plastic injection molding, there can be a knowledge gap in making sure the CAD model is properly designed for this manufacturing process.

There are certain, very specific design features that must be considered in the design stage in order to avoid moldability issues that can produce undesirable results in the molded parts. If they’re not considered from the beginning of the design process, and they’re not discovered until the Design For Manufacturability (DFM) review, design changes can add time and cost to an injection molding project.

Draft angle is one example. If a part does not have draft angle designed into it where needed, it may not eject from the mold cleanly and smoothly, and the part will have to be redesigned with proper draft angle.

To help avoid costly and time-consuming design mistakes, we created a plastic injection molding design guide. It provides information on the most important design requirements so they can be incorporated at the initial design stage.
